The maintenance of atomic energy-related facilities has been performed mainly on the vibration method until now. However, for the maintenance in atomic energy-r elated facilities and the fact of the rotary apparatus, it is not enough at all only by the vibration method. We note the SPM method as a technique to watch th e bearing condition in accord with those facts and carried out verification. We wrote about a background of starting this verification, the principle of the SPM method, contents of the verif...

Higashidori Nuclear Power Station, start-of-operation in December 2005, is a relatively new plant. We decided to get original data of air duct c ondition to determine maintenance policy of air duct, because planned maintenance of air duct has never been done and the corrosion of air duct has occurred in other plant. In January 2014, we found a corrosion-hole at the downstream of the inlet damper in the ventilating air conditioni ng system for Main Control Room (MCR). We supposed that the cause of rapid cor...
